Automotive manufacturers and suppliers of electronic control units (ECUs) will be challenged more and more in the future to reduce costs and the time needed for ECU development. At the same time, increasing requirements concerning exhaust gas emissions, drivability, onboard diagnostics and fuel consumption have led to the growing complexity of modern engines and the associated management systems. As a result, the number and complexity of control parameters and look-up tables in the ECU software is increasing dramatically. Thus, in powertrain applications especially, calibration development has become a time-consuming and cost-intensive stage in the overall ECU development process. This paper describes the current situation in calibration development and shows how the new dSPACE Calibration System will face this situation. It provides an overview of the main benefits of the tool, which has been designed in close cooperation with calibration engineers.

Due to the rapidly increasing number of electronic control units (ECUs) in modern vehicles, software and ECU testing plays a major role within the development of automotive electronics. To ensure effective as well as efficient testing within the whole development process, a seamless transition in terms of the reusability of tests and test data as well as powerful and efficient means for developing and describing tests are required. This paper therefore presents a new integration approach for modern test development and test management. Besides a very easy-to-use way of describing tests graphically, the main focus of the new approach is on the management of a large number of tests, test data, and test results, allowing close integration into the automotive development processes.
